    • Assessment and Mitigation of Non-Circulating Bearing Currents in Bridgeless Rotor Synchronous Reluctance Machine 

      Vostrov, Konstantin; Nutakor, Charles; Parviainen, Miika; Lindh, Pia; Pyrhönen, Juha; Sopanen, Jussi
      Proceedings of the IEEE international electric machines and drives conference (IEEE, 04.07.2025)
      Bearing currents in electric machines can lead to surface damage to bearings and eventual machine failure. Non-circulating bearing currents resulting from high-frequency common-mode voltages interacting with parasitic ...

    • Effect of Parasitic Capacitances in Drum-Winding Machine 

      Vostrov, Konstantin; Singh, Shruti; Petrov, Ilya; Pyrhönen, Juha
      Proceedings of the IEEE international electric machines and drives conference (IEEE, 04.07.2025)
      Most electric machines utilize lap-type or wave-type winding. For those machines, the parasitic capacitances and bearing current phenomena are well studied. However, there are cases where drum winding is favourable, such ...

    • Non-Circulating Bearing Currents in Drum-Winding Machine: Threat Level and Role of End Windings 

      Vostrov, Konstantin; Petrov, Ilya; Singh, Shruti; Pyrhönen, Juha
      Proceedings of the IEEE international electric machines and drives conference (IEEE, 04.07.2025)
      Bearing currents are a significant challenge in electric machines, particularly in variable speed drives with modern fast-switching frequency converters. This study focuses on non-circulating bearing currents in drum-winding ...
